Macrocell
The macrocell consists of a storage element, routing resources, a clock multiplexer, and initialization
control. The macrocell has two fundamental modes: synchronous and asynchronous (Figure 5). The mode
chosen only affects clocking and initialization in the macrocell.
In either mode, a combinatorial path can be used. For combinatorial logic, the synchronous mode will
generally be used, since it provides more product terms in the allocator.
